I have a game elements pc recoil gamepad from wal-mart. I plug it in, and everything's fine. But I always seem to move forward in games without press up on the left joystick, so I went into calibration and it always seems that when i move the left joystick, instead of bouncing back to (127,127) it goes to (140,102). I have tried it on another computer and it works just perfectly. I have windows xp pro sp2 and the other computer has Windows XP Home w/ SP2. How can I correct this?
